Table 2.

The time consumed by the three algorithms (s).

Data set	RBF-RCE	SVM-RCE	RF
Colon	15.23	30.29	27.24
GLI	945.38	None	2874.52
DLBCL	124.25	377.56	207.43
Prostate	179.33	665.81	371.64

The bold value indicates that the algorithm is most efficient, and the shortest time consumption is handled in the same data set.
